The political role of Norwegian media is very much an individual opinion, and opinions vary. This compares very much to the discussion of for example Fox News: Are they "tough and vibrant", or are they "not a news organization" (quotes from other entries in this story). I'd wager that in Noway, most people disagree with the opinion voiced above, but your milage may vary.
Government subsidies take many forms. The major part of press subsidies in Norway is a tax break, where there are little to no opportunity for political intervention, but there is also a significant flow of direct money.
Svirre seems to believe that the largest takers of subsidies are the same that are "publishing fronts for [the] four leftist political parties". Ignoring the discussion of "leftist", this is factually wrong. The number 2 receiver is the newspaper called "Vårt Land", the major christian conservative newspaper in Norway. Google translate says this about their self-proclaimed mission: "Vårt land should be an independent daily newspaper for people who want to read about the most significant is happening, and about faith's role in this. The newspaper will administer the Christian faith and thought, and help to ensure that this will dominate the society and people's lives and choices."
It is a fact that Norwegian newspapers enjoy readership that is amongst the highest in the world, with 550 600 copies are sold per 1000 inhabitants. This may or may not be related to the government subsidies.
